If there is even a hit of shudder with the wheels, bring them back and get them rebalanced. I have been known to do this repeatedly.

Before you go, check all of the tires. I once found a tire that was mounted backwards, the tire had a little arrow indicating direction flow. My current tires say 'this side faces out'.

As for alignment, a tire swap should not cause any alignment problems. Perhaps the kid put the lift on a suspension part and bent it? Most shops do not do alignments, a very expensive machine is needed. A good alignment shop will charge $80-100 for a front wheel drive car.
